the linef-t of Fig. 2in the direction ofl This invention relates to feeding'devices andmore particularly to dial feedlng appa-l ratus for punch presses.

In manufacturing parts =on a quantity productionV basis, they parts are assembled or formedl on a'punchV press having-a rotatable dial thereon, :on which the parts are positioned .by an operator; The'parts are carried tothe punchingposition ofrthe press, worked, upon bythe press, and moved Varoundrto a position where a: seconds operator. removes themsfrom the dial. v

An object of thisv invention is the provision ofi' a simple, safe andl eflicientv dial feeding 5,- unitfadapted to bef readily `and quickly secured to ablanking, forming, drilling or other processing machine- .Y

In accordance with oneembodiment, the

punchpress to transmit` motion therefrom,

througlia train of gears, and aiGreneva` geartouimpart rotativel motion! intermittently to a dia-lifor-feedingpa-rts tothe punch and' die-o-fthepunch presseV Allof the aforementioned moving parts-.are enclosed :in suitable` housings 'topreventfinjuryto an operatorV and are alsoxconveniently'arrangedto facili,-

. tate mounting. There is also provided a pin operable in'res'ponse to therotation of'the'Greneva gear to accurately position and lock the dialin position after the completionof each partial rotation thereof.

Other, featuresfand` 'advantages of the invention will become apparent i, from the 4following description of; oneiembodiinentz thereof, reference being had: toA the accompanying drawings, wherein Fig: 1 isa fragmentary"front'felevational view of a' punch' press equipped with(` a feed"y mechanism embodying the features of this invention; -Y

Fig. 2 is a horizontal sectional view taken on the line 2-v-2 of Fig. l in the direction of the arrows;

Fig. 3 is a fragmentary horizontal sectional view taken on the line 3-3 of Fig. l in the direction of the arrows; and

Fig. 4 is a vertical sectional view taken on the arrows.

Referring` nowito `the drawings wherein` tion thereof: extending beyondrthe front ofy the bed 7 has abushing 115v secured `thereto by i means ofa nutl. Journalled in the bushing is a hollow taperedspindle 17 iwhich is secured in the bushing by-a nut 18' anda locknut`19, a suitablewasher 20"-being positioned between the nutf 18- andl the end of` thebushing.`

The upper end of the hollow spindle 17 .has afdisk22l secured thereto by means of 'screws 22-22 andhas a headed member-23 positionedtherein and keyed thereto by a key 24: which is.l positioned inakeyway 25 cut in the spindle.. A headed sleeve 26 .is threaded inthe lowerfend of'the hollow spindle and has a bolt 27 passed therethrough which is threaddin'the lower endfof'the headed member 235 thereby Securing the headedmember side' ofthe disk 21V by screws'3vly-3l.

Rotative motion-is impartedV intermittently Y to theGeneva gear 30hy adriving roller y32y mounted on a spur gear 33 which is rotatably Vjourna'lled'in thebed plate'13 andlwhi'chv meshes with a smallgearf 34 also journ'alledY tative motion from'a' gear 35'which is secured headed"l in the'bed-plate. The gearf34re'ceive's its ro'v 1-'60 m one of .the slotsv in thefpGeneva kgear 30`to to a collar 36 pinned to la rotatable shaft 38 by a pin 39, bolts 37-37 being provided for securing the gear 35 to the collar 36. The rotatable shaft 38 has a beveled gear 40 secured to its upper end by means of a pin 41 which beveled. gear meshes withga second beveled gear 42l pinned to the crank shaftll journalled in a member 45 which has an an-v nular portion 46which encircles an eXten- Y zesV sion '47 of the beveled gear 42. The beveled gears and 42 are held in mesh by means of a nut l48 threaded on the end of the extension 47 ofthe beveled gear-42, a suitable washer .49 48- and the being positioned betweenthe nut portion 46 ofthermember 45.

,An irregular shaped housing member 50 covers the gears 33l and v34fand supports a pair of bushings 51 and 52 inwhich a locking pin .53 is slidably mounted. The locking pin 1 has a collar 54secured thereto in a'depending. :portion 55 of which a cam roller 56 is mountedl forv engagement with a Vcam mounted on and rotatable with the spur gear 33. Positioned about thepinf53 and between theibushing 52 and the collar 54 isaz spring'58 which urges the pin.' to the left (Fig. 4) and at predetermined intervals vinto engagement with one of a plurality o'fbushings 59 mounted on the periphery of the disk A21` to secure the'dial tothe'engagement of aas'lotk inthe Geneva 28` against rotation.V

The gear 35 is covered byf a which a V-shaped bracket 61 is positionedfor supportingfa sleeve 62 which encloses the 'shaft 38.' At its upper end, the sleeve 62'i`s secured to the member 45 which alsoj sup-A ports members 63 and'64 which house the Y y bed plate, a unitary feeding device adapted to be removably Asecured as a unit tothe punch bevel gears 40 and 42. It is believed that a clear understanding of the features lof thev invention will be had byr referring to the following description of the Voperation thereof. y The bed Vplate 13 having been'secured tothe'bed of a press, and thev gear 42 having been secured to the crank shaft thereof, upon rotation of the VKcrank shaft the gear 42 lwill drive the-gear 40 and a shaft '3 8 securedV thereto and thereby im-j part motion through the gears 357and 34 to the gear 33 carryingthe Geneva gear driving member 32. Once in each, rotation of the gear 33 'the driving member 32V will engage impart motion'to the dial 28. Just yprior gear. by thedriving member 32`the cam? will be effectiveto move the cam roller andV f the shoulderin 'which the cam rolleris'rr'iountsV Lev/1,414

member Over-same rigidly and accuratelyin'position beed to the right to withdraw the locking pin 53 from a bushing 59 in the disk 21. Just subsequent to the disengagement of the driving member 32 from one of the slots in the annular Geneva gear the cam 57willbe effective toy permitthespring 548 to move the pin 53 into one'of the'bushings59 kin thedisk 2l to accurately position Va part, not shown, under the punch of the punch press.

The operation r'described hereinbefore will be automatic-ally repeated vas long as the crank shaft of the punch press is rotating and will be effective to move successive blanks .into Vposition to be operated upon the punch and die of the punch press.
